Tips for the Best 3 Ingredient Oatmeal Cookies

  • Overripe bananas are best. The peels should be covered in brown spots for the best flavor and consistency. 
  • Adjust the texture. If the dough feels too wet, add more oats to achieve a better consistency.
  • Use the right oats. To achieve the ideal chewy texture, opt for old-fashioned (or rolled) oats. While you can use quick oats in a pinch, they will alter the texture of these 3 ingredient oatmeal cookies.
  • Let the dough rest for a few minutes before scooping. This gives the oats a chance to absorb more of the moisture, creating perfectly soft and chewy cookies.

Variations for 3 Ingredient Banana Oatmeal Cookies

  • Experiment with different mix-ins like raisins, chopped nuts, or dried fruits for a twist on your 3 ingredient oatmeal cookies.
  • Adjust the sweetness by using honey, maple syrup, or any other natural sweeteners according to your taste.
  • Swap out the chocolate chips for raisins and add a dash of cinnamon to no egg oat cookies dough for a classic oatmeal raisin cookie.
  • Though these easy oatmeal cookies are made without peanut butter, you can definitely add some if you prefer!
  • Make even simpler treats with 2 ingredients by leaving out the chocolate chips. Keep in mind that you won’t be able to get as many cookies out of each batch.

How Ripe Should Bananas Be For Cookies?

It’s essential to make sure you use overripe bananas for these easy oatmeal cookies, as their natural flavor is the main source of sweetness in these 3 ingredient oatmeal cookies. There should be lots of brown freckles over the entire peel — the more the better!

To ripen bananas quickly, place them in a brown paper bag and fold it shut. 

Need them to ripen immediately? Preheat your oven to 300 degrees F and place unpeeled bananas on a foil lined baking sheet. Bake for 15-20 minutes, then cool and scoop out the flesh. You can also use your air fryer at the same temperature, but cook for about 8 minutes instead.

Can I Freeze the 3 Ingredient Banana Cookies Mix Before Baking?

Sadly, you can’t. Bananas produce a lot of water when thawed, so your 3 ingredient banana cookie will end up a soggy, flavorless mess when baked.

However, you can freeze baked cookies! Allow them to cool before transferring to an airtight container or freezer-safe storage bag. 3 ingredient oatmeal cookies will keep for up to 3 months in the freezer — just thaw on the counter when you need a quick snack.
